I was quoting Batman, not you Enkrypt.


Here's some more specific info


http://en.wikipedia.org/wiki/World_Geodetic_System


As of the latest revision, the WGS 84 datum surface is a pole-flattened (oblate) spheroid, with major (transverse) radius a = 6,378,137 m at the equator, and minor (conjugate) radius b = 6,356,752.314 245 m at the poles (a flattening of 21.384 685 755 km, or 1/298.257 223 563 ≈ 0.335% in relative terms). The b parameter is often rounded to 6,356,752.3 m in practical applications.


0.335% off from being a sphere.  Close enough for me :).
